How does the fishing industry affect the environment?

What is the problem with the fishing industry?

Problems such as overfishing, plastic pollution (as explored in the documentary Seaspiracy), habitat degradation and bycatch (capturing unwanted marine life when fishing for a certain species) are imposing drastic consequences that have a ripple effect across the entire planet.

How does overfishing destroy the environment?

Coral Reef Destruction Of the world’s coral reefs, 55 percent are affected by overfishing. When a fish population declines, algae can grow unchecked and eventually smother corals.

Why is industrial fishing bad?

Industrial fishing has been responsible for harmful environmental impacts. Overfishing can deplete resources, many animals like dolphins and sea turtles are products of bycatch, and the massive vessels used require large amounts of CO2-producing fuel.

Is fishing good for the environment?

Angling and fisheries conservation Anglers play an important role in protecting and conserving the aquatic environment. They act as custodians of the waters they fish and are often the first to notice and report pollution incidents or other environmental issues that need addressing.

Is fishing environmentally friendly?

How does fishing affect water quality?

“When the bait dies and breaks down, it basically contributes to organic material and nutrients which will affect our water quality (because) all these nutrients will enhance algal growth.”

How destructive is the fishing industry?

Around the world, commercial fishing is decimating fish populations, threatening countless other marine species, and destroying crucial habitats. Our food system claims the lives of over 9 billion animals each year.

How much waste does the fishing industry produce?

More than 100 million pounds of plastic from industrial fishing gear pollute the oceans each year—threatening marine life.

What is the biggest polluter in the ocean?

One of the biggest sources is called nonpoint source pollution, which occurs as a result of runoff. Nonpoint source pollution includes many small sources, like septic tanks, cars, trucks, and boats, plus larger sources, such as farms, ranches, and forest areas.
